lVlIACvI-IINERY` FOR `MAKING TIRES BY CONTINUOUS ROLLING.`

. speeiacation or Leners Patent Nja. `7,968, dated March 11`, 185,1.

To ,ZZwhomwt may concern:

Be it known `that I, PERRY G. GARDINER, of the city, county,and Stateof New York,

i have invented anew and useful improvement on a. machine to rolllralroad wheeltires from `an annular `inass of iron with a hole in the center without lop or other welding of the two ends of a bent-bar; and I do hereby declarethat the following is a full, clear, and exact description ofthe construction and operation ofthe same, reference being had to theannexed drawings, making a part of this specification,` 1n which-` i Figure l is a side andF ig. Q is an end elevation;`Fig. 3, is a section on a line "from X, to (see Fig. l),` i "1 ,n The letters marked in the drawings indicate like parts inallof the figures.

rolledinto a tire; and making `The nature of my invention consists in giving, or furnishing a self` acting and `adjustable meansof arrestingmoton (either way) of the top shaftyandforming roller placed thereon, in making tires for` raili road `car `or locomotive wheels-from fa,

mass of iron formed the bloom or `piled and welded from bars or slabs,

byany ordinary means into a must have an appropriate quantity or weight of metal to make a given section and` diameter or tire. It is important thatthe rollers cease to act at `the precisetime, to secure the required diameter of tire to fit the wheel upon which it is thereafter tobe set.`

In short, to roll such tire by the measure lor judgment of the eye is in point of economy, impossible; but ifthe operator has/the ad- Justable means by set screws or otherwise,

to trip a swaybar, throw out of gear cog;

wheel work, or slide a belt on aloose pulley, he may by a few experimental trials, arrive atthe exact point at which to arrest theadvance and approach of the forming roller; and having `ascertained this point, so set the parts fixedly, and by these means trip a lever, slide or move parts necessary toa stopping effect; sothat all that remains of nicety to the operator to do, is to weigh accurately the mass of` iron to be wrought or y simple and easy that which would by the ordinary means ofdoing it tbe diihcult of attainment.

I will now proceed to the general description of themachine, and afterwards, point out the parts which I deem tobe new and forged circular flat` piece with a hole in the `centerythe piece slide flangesfc, tion to their seats on which they slide up 4and down. e y y i CZ, d, are` studs secured tothe slide boxes `hubs next to the clutch i clutched by the and patentable A, theroller stands, made and secured in the ordinary way. B, the top main shaft; C, the lower main and the driving shaft of the machine; D, the top andE, the lower forming rollers: F, the guide roller, with double flange at the side lof the face, to receive and hold in position, the tire as it leaves the forming rollers, and to prevent the` tire from warping out of shape edgewise; which by a heavyreducit-ion at the side forming the tread, is inclined guide roller is placed upon so to do; such shaft (3W-which together with the forming i rollers, are overhung their bearings at the l outside of thestands for the convenience of approach to` them, with the work to be done; `which shaft G, lturns in slide boxes H, H, fwhich have their` seats `at b, upon the stands Afthey hook on to the back side of c, which hold them-in posi- H, H, and `enter loosely slots in arms e, e,

is attached, and which through the parts `just named, inimmediate connection with `the gu1de roller-the same is operated by the hand of the operator. The said rock shaftI, has its bearings in eyes madein the lstands A, which at thesection required, are

of such width, as to admit of the same, without rendering the standweak and defective.`

K, is a cone of pulleys, turning loose on vshaft L, and in line with a corresponding cone M, keyed fast to shaft C; which firstnamed cone K, is operated and put in motion, by thecross belt f.4

N, is a loose pulley on shaft L, the saine is driven by the pulley O, p (keyed fast `to by the open belt g. `Placed beso clutched to pulley K, downward motion is given to the top shaft` carrying with it, the top forming roller; if elutchedto pulon rock shaft I, to which the hand lever J, i

ley N, the reverse is the case with such shaft and roller.

Q, is a clutch arm on rock shaft R, which last named shaft, turns in eyes on stands Sfastened by screws It, to cap plate T, and on which shaft R, is fastened-an arm, or trip lever U, which operates the clutch sleeve V; W, is an arm firmly and strongly attached, by tap screws, z', c', z', z', and z', (see Fig. 3) to the inside of the upper journal box, or cap of the shaft B, it being the up and down movable shaft; which arm WV, is furnished with regulating and set screw, la, at the lower projection and part of arm, and a similar screw j, at the upper part; which arin of course rises and falls, corresponding with the up and down mO-vement of the top shaft B-being fastened to it; when moving downward, the set screw y', will make contact with the 'trip lever U, at Z, and through the clutch arm Q, slide the clutch sleeve V, on the shaft L, freeing the clutch from the pulley K, arresting rotation, and stopping the shaft L, upon which, the downward movement of the top shaft is dependent, and cease to reduce the tire between the rollers, but if the clutch sleeve V, be moved into contact with pulley N,-reverse motion will be given to such top shaft; but the motion upward will be arrested in its turn, by contact o-f the screw 7c, with the said trip lever U; there is suicient space on the shaft L, for the clutch sleeve V, t0 remain unclutched to either of the pulleysV K, or N if desired; in which case the top shaft will be at rest-as to up or down motion. And the trip lever U,- by the handle m, is worked by hand, to commence a movement of the top shaft-up or down, by clutching either way, as the case may require; Y, Y, are right and left hand screws-or worm gearing on shaft L, working into screw wheels P, which wheels are fastened to, and drive the main screws X,

X, that give effect to thetop shaft; such screw wheels P, are keyed fast to the nuts Z, Z; the cap plate T, is held down upon the top ofl the stands, by large screw bolts n, which pass up through the stands in the ordinary way; the nuts, Z, Z, are provided with heavy heads or collars at p seen under the cap T, at Fig. 2, which with the screw wheel P, hold the nuts in position. The main screws X, X, are attached to the caps of the upper journal boxes-embracing the lower part of the boX by large screw bolts r passing through the box, cap, and a plate S, (see Fig. 3,) under which plate the head on screws X, X, turns, and is secured.

What I claim as new and desire to secure in Letters Patent is,

l. Stopping the advancing movement of the movable toward the stationary roller, when the tire shall have attained its proper section, by means of selfl acting mechanism, acting and constructed substantially as herein described.

2. I also claim the combination of belts, pulleys, clutches, screws, and screw wheels, with the sway bar and triggers, by which a self acting advancing and retrograding motion is given to the movable roller, each motion changing to the other when caused so to do, by the hand of the operator, but self arrested and stopped by the set of the triggers, substantially as specied.

P. G. GARDINER.
